"java.lang.NullPointerException"

Hi,
I'm writting you because I need some help with a problem.
I'm trying to integrate RapidMiner with BizAgi Studio using a Web Service, and when this one wants to run a Process I have a java.lang.NullPointerException.
I don't know why is this happening because when I run the process by itself in RapidMiner I don't have any problem (using the same files).
Here it's the XML log:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>

without knowing your code and your data it's hard to say anything. But it seems that you are using RapidMiner 5.1.006, which is quite old. Maybe you could try to update to the latest version and test if it works with the newer version.
Furthermore the warning on top states that your model has been trained on 0 attributes - are you sure you correctly trained the model and saved it at the location from where you are trying to load it now? To apply it on your test dataset with 21 attributes, also the training dataset should contain 21 attributes.
Best,
Marius
Thanks for your reply!
I changed the version of RapidMiner and also checked the model.
Now I don't have that problem.
But I don't know why the log says:

Can you please help me again???
Thanks!
your log says
INFO: Cannot access file system in execution mode UNKNOWN. Not loading repositories.
Did you set RapidMiner's execution mode via the RapidMiner.setExecutionMode? You probably want to set sth. like COMMAND_LINE.
Best,
Marius
